If you want to see how I made this (and how you can too!), visit my HDR Tutorial. I hope it gives you some new tricks!
This is one of the largest pieces I have ever made; the giant TIFF is about 21,000 pixels across (this one I uploaded is only 15,000 pixels across and has been downgraded to JPEG to fit inside the draconian upload requirements). I shot it one cool and crisp morning at Glacier National Park in this crystal clear lake that is fed by glacial runoff. It is comprised of 90 different photos that took a small eternity to mix together into an epic HDR. I've been thinking about having a 10-foot mural printed at walk-up resolution... but I am not quite sure where I would put it!
